divide by zero.

so coke has come out with new "portion controlled" 7.5oz cans. this makes sense for the high-fructose-corn-syrup-impregnated beverages.

but they've also come out with 7.5oz cans of diet coke and coke zero. how do i know? we got a free 8-pack of the coke zero cans yesterday due to a supermarket promotion.

now. a 12oz can of coke zero is 0 calories. a 7.5oz can of coke zero is... yes. 0 calories. so why go through the effort of "portion controlling" a zero-calorie beverage? we switched to coke zero a while ago, because it does taste more like real coke than diet coke (ew).

but i'm a little confused by the purpose of this product. unless it's for people like me, who can barely finish a 12oz can of coke (unless i'm deydrated or eating something salty). but given the whole no-calorie thing, what would prompt me to stop buying cases of 12 12oz cans, and instead buy 8 7.5oz cans? the financial difference is miniscule. the calorie difference is nonexistant. why did they bother?
